The Outreach DAC is an intermediate-sized catheter designed for use with the Merci clot retriever in acute stroke. We investigated its utility as an adjunctive device during AVM pedicle embolization. In the authors' opinion, the DAC provided additional guide-catheter and microcatheter support, improved selective angiographic visualization of AVM angioarchitecture, aided microcatheter removal from its embedded position in the AVM Onyx cast, and enhanced local microcatheter control and safety, compared with embolization with the guide and microcatheter alone.
outreachDAC 是一种中等尺寸的导管,设计用于与 Merci 取栓器一起用于急性脑卒中。我们研究了它作为辅助装置在 AVM 供血动脉栓塞中的效用。作者认为,DAC 提供了额外的引导导管和微导管支持,改善了 AVM 血管构筑的选择性血管造影可视化,有助于从 AVM Onyx 铸型中的嵌入位置取出微导管,并增强了局部微导管控制和安全性,与单独使用导引导管和微导管进行栓塞相比。
